ABSTRACT

This study focuses on sound sequences where it is ambiguous whether it is just a transition between segments, or a glide. /j/ is defined as a transition from [i], and /w/ is defined as a transition from [u] or [o], making it challenging to determine whether there is a glide in [i(j)ə] or [o(w)a]. The purpose of this study is to examine whether /iə~ijə/ and /oa~owa/ are distinguished and, if they are, to identify which enhancement is applied. The formant trajectory of the vowels was observed, and the lengths of the preceding vowel, transition, and following vowel were measured, as well as the pitch and intensity of the transition parts. The results show that /iə~ijə/ are rarely distinguished, whereas /oa~owa/ are relatively distinguished. When speakers distinguish between them, the articulatory features of the preceding vowel are emphasized in sequences containing the glide. Additionally, the pitch and intensity of the transitions are higher in sequences containing the glide.

Keywords: transition; glide; enhancement; formant trajectory; length of preceding vowel and transition; pitch and intensity of transition
